6 FAQs about [Photovoltaic panel counterweight construction example]

Should PV panels be considered as dead load?

The latest ASCE version (2016) now requires the PV panels to be considered as dead load. This can cause major complication in determining the total system weight especially in high seismic regions. Also, live load should not be considered on the roof if the panels were placed at specific distances and heights.

Do rooftop solar panels add weight to a building?

For a steel or wood low rise building, the relative additional weight from rooftop solar panels can add approximately 10% to the total factored design load of the roof structure. However, when considered in light of the total building costs, this additional costs may prove to be minimal.

How much weight can a ballasted PV system impose?

The weight loading of different systems and their installation methods should always be considered. A ballasted PV system on a building in an exposed location can impose loads as high as 60 kg/m² which can impact both structural stability and compress waterproofing membranes and insulation.

Can PV panels be installed on a new roof?

For example, some jurisdictions in CA and CO now require PV panels to be installed on certain new roof structures. The primary code used by structural engineers in the determination of applicable loads on buildings is ASCE 7: Minimum Design Loads for Buildings and Other Structures which is adopted by reference in the IRC and IBC.

How many kN/m2 is a PV panel?

As noted previously, the uniformly distributed load due to the PV panels is 0.13 kN/m2. The panels are to be installed to the top 3.4m of the slope of each roof, therefore the dead load on plan for each roof will be as follows: Imposed loads have been derived in the basis of BS6399-2: 1997 (Wind Loads) and BS6399-3: 1988 (Imposed Loads on Roofs).

What are some common structural issues related to roof-mounted PV panels?

To best illustrate some common structural issues related to roof-mounted PV panels, the following examples are provided. Several years after PV panels were installed on a residential roof located in New England, the homeowner reported the roof was exhibiting a downward deflection (“sag”) and cracking of the rafters.
